In a statement posted on the band’s official website yesterday (June 11), it was confirmed that gigs in Dallas, Woodlands and New Orleans will no longer go ahead on the planned dates while Dwane recovers from surgery.

The statement explained: “Our friend and bandmate Ted has been feeling unwell for a few days, and yesterday he was taken to a hospital to receive emergency treatment. The scans revealed a blood clot on the surface of his brain that requires an operation. Ted is receiving excellent care and we are being assured that he will recover quickly from surgery.”

The band, who headline Glastonbury Festival on June 29 and T In The Park this summer, added: “We have no plans to cancel or postpone any other appearances along this current tour.”

Along with headlining Glastonbury Festival, Mumford & Sons are scheduled to play their biggest ever headline show at London’s Olympic Park on July 6. The outdoor event, which is the first non-festival headline show to take place on the renovated London 2012 Olympic Games site, will also feature Vampire Weekend, Ben Howard, Edward Sharpe And The Magnetic Zeros, Haim and newcomers Bear’s Den, all of whom were handpicked by the band.
